Iron Ware versions and sFlow

I have a pretty large mix of FESX devices running various IronWare releases and I'm getting erronious exports on one units running 4.x.x code. All I'm getting is counter data every second and maybe 1/50,000 packets or less even though my sample rate is 1/4096.

All the 5.x.x based boxes are exporting flows normally.

I also notice that the CPU usage is around 20% at full tilt with sflow enabled on the 5.x.x codebase but stays at <1% on 4.x.x

Can anyone confirm sFlow pretty much broken/useless on the 4.x.x codebase?

I can confirm that on 4.2.00c on the TI24X, we get exactly 50 samples per second exported from our boxes, regardless of the actual load and regardless of the configured sampling rate. I've opened up a support case about this.
